HITCHING DEVICE.

SPECIFICATION forming part of Letters Patent No. 323,022, dated July 28, 1885.

(No model.)

To aZZ whom it may concern.-

Be it known that I, WILLIAM G. BOONE, of Brooklyn, in the county of Kings and State of New York, haveinvented an Improvement in Hitching Devices, of which the following is a specification.

The object of this invention is to provide a simple and efficient detachable ring-fastening for hitching-posts and the like; and it comprises certain novel combination of parts whereby the device may be readily attached to and detached from the hitching-post or other support, thereby avoiding the necessity for the cumbrous and expensive operation heretofore required in attaching hitchingrings, &c., to their posts or supports.

Figure 1 is a side view and partial sectional View of a device constructed according to my said invention. Fig. 2 is a like view, taken in a plane at right angles to that of Fig. 1. Fig. 3 is a transverse sectional view, taken in the line 90 of Figs. 1 and 2. Fig. 4 is a view taken in line 3 y of Figs. 1, 2, and 5. is a longitudinal sectional view illustrating the internal construction of some of the parts indicated in Figs. 1 and 2; and Fig. 6 is aside view illustrating a modification ot' mysaid invention,

The sectional lines at A in Figs. 1 and 2 indicate the material of the hitchingpost placed in position for use, which latter may be substituted by the side of a building or by a stone, block, or by any suitably strong or solid support. In the post or support, whatever the same may be, is formed a cylindrical hole or bore, a, of suitable diameter.

B is the ring or annulose device through which on occasion is passed and tied a halter, lariat, or strap, by which the horse or other animal is to be secured. This ring swings in a head, 0, in which it is properly socketed. This head 0 has a bulb or knob, D, connected with the head by a neck, b. D is placed in acorrespondingly-shaped socket in a block or boss, E, which is provided upon the outer end of a bolt, F.

It will be observed that the head 0, and

consequently the ring B, is connected with The bulb or knob.

The inner portion of the bolt F is provided with a screw-thread, a, which screws into an internally-threaded sleeve. G, the opposite sides ofwhich are madesloping to give a wedgelike shape to the inner end of the sleeve, as shown more clearly in Figs. 1 and 5. Placed upon the opposite end of the bolt is another similarly-tapered sleeve, H, the outer surface of which bears against the inner surface of the boss or block E.

I I are the two longitudinal sections which form the expanding sides of the device, and which are placed around the bolt F, as shown in Fig. 4. Each end of each section is beveled or made sloping at its inner side, with an inclination corresponding in angle to the slope of the adjacent sleeves G and H-that is to say, such is the construction represented in Figs. 1, 2, and 5-but when desired, as is hereinafter explained, only one sleeve may be used in such case, but one end of each section will need to be beveled, although a more effective operation of the invention is seen red when the two tapered or wedge-like sleeves are used, as indicated in Figs. 1, 2 and 4, as aforesaid. WVhen the said sleeves are caused to approach each other, their sloping or tapered or wedge-like surfaces act upon the inclines a at the ends of the sections and force the same laterally outward. Each of the sections I has a transverse groove in its outer surface, so that when the said sections are placed together upon the bolt, as described, these grooves, taken collectively, form a circumferential groove, 0, in which may be placed a wire band, d, to retain the sections in place under the conditions of ordinary handling or storage, and also to assist the retention of the sections 1 in place during the operation of placing the expansion-bolt in the holein which the same is to be affixed or attached. This wire should be of such a character as to yield readily to the expansive action of the bolt, as hereinafter described.

In applying the apparatus to use the expansion-boltthat is to say, the part which comprises sections I and their necessary adj unctsis thrust into the bore, hole, or opening provided, as hereinbefore explained, to receive it, which done, a wrench of any suitable character is applied to the block or boss E, and the bolt F is turned in such manner as to draw the sleeve G toward the said block or boss E,

so that the two sleeves G and H, acting upon the inclined or sloping extremities of the sections I, force the latterradially outward against the internal surface of thebore, hole, or opening in which they are placed, and thereby tighten and grip the same against said surface with a force and tenacity sufficient to insure the retention of the device in place against any strain brought upon the object in ordinary or even unusual exigencies of use. The expansion-bolt portion of the device-that is to say, the portion comprising the sections I and their necessary adjuncts, as aforesaid-being thus firmly fixed to the hitching-post or other support, and the ring B having, as hereinbefore described, a swivel connection with the portion of the device affixed as aforesaid, the

said ring is enabled to turn as is required for the convenient and useful employment thereof in securing horses or other animals.

In the modification shown in Fig. 6 the sections I have their outer ends resting against the block or boss E, while their inner ends only are beveled and in due relation with the tapered sleeve G, screwed upon the end of the bolt F, as hereinbefore explained with reference to Figs. 1, 2, and 4. Vith this case the expansion-bolt is expanded only at its in nor end, as illustrated in said Fig. 6. This construction will be found measurably effective under all conditions where only a moderate strain is to be exerted upon the device; but where greater resistance to strain is required the construction represented in Figs. 1, 2, and 5 is to be preferred, inasmuch as in the latter case the lateral expansion of the bolt is uniform throughout the length of the sections I.

When it is desired to remove the device from the hitchingpost or other support, it is only necessary to turn the bolt F in a reverse direct-ion, thereby permitting the sections I to retract.

What I claim as my invention is The combination, with an expanding-bolt, of a ring, B, head 0, having bulb D, and block or boss E, having a socket for the reception of the said bulb, substantially as and for the purpose herein set forth.
